Abstract (en)
[origin: ES8304232A1] A circular loom is disclosed for the manufacture of tubular fabrics made of threads and/or strips of polymeric materials. The loom is of the type having heddles on two concentric circles and a central driving shaft, which comprises, for the alternate spreading apart of the warp threads, a support member, mounted coaxially and rotating around the central and vertical loom shaft, on which support one or more pairs of wings or flyers or circular sectors diametrically opposed to one another are coupled under a predetermined and fixed angle of inclination in respect of the axis of said central shaft, each pair of wings or circular sectors being coupled in an inclined manner on said support member with interposition of a roller bearing so as to prevent said wings, through means connecting such wings with fixed parts of the loom, from rotating around said support member when the loom is working and thus assuming a continuous undulatory motion, the end portions of said opposite and oscillating wings or circular sectors being connected, through a plurality of tie rods, with eye-bearing elastic members and having the function of elastic heddles so as to transfer the undulatory motion of said wings to said elastic heddles and therefore to achieve, along the development of the loom reed and by using additional pairs of wings, the necessary spreading apart of the warp threads which is suited to form the wave shed or pitch, rolling means associated with conventional shuttle pushers being furthermore provided for the shuttle drive.
